Rotax 915is and VPX installation discussion

Thanks for the feedback Eric. It sure would be easier if Rotax just took care of the start power and just had a single aux power input.

How about locating the momentary switch just to the left of the throttle. Wrap your hand around the throttle and use your thumb to pull in the momentary switch. When it starts, let go of the momentary but you still have the throttle controlled. I think that's actually how Kitfox does their panels.

This however is a great post that I am certain is going to help a lot of people out. Thank you

The start-power switch is indeed close to the throttle on the Kitfox 912is panels but I was not able to get my hand on both simultaneously.
Maybe my hand is just too small

I Have this setup. I used a three way switch for the start power. On-off-momentary. I placed it behind a trigger guard. My switch is just right of the throttle. I can lift the guard, it parks and stays up. I can use my throttle hand (while holding the throttle ) to push down on the momentary switch if I choose but I throw that switch up to the on position and wrest my hand on the throttle. Once I have controlled the RPM to 2000rpm I throw the guard down over the switch which automatically returns that switch to the off position. I have forgotten to throw the guard down but seem to catch it quickly when I look at the throttle and see that the guard is still up.

Page 12 of "show us your panel" you should find my pic.

Does anyone know how I can determine exactly what type of signal the 915is Lane A and B switches generate? It's just
connected between 2 pins on an engine connectors HIC-A and HIC-B. Is 1 pin ground and the switch just connects the other pin to ground
or is there power on one side and switch connects power to the other pin?

Eric, you implied that it's the former but is there a way to verify this? Maybe someone that has a 912is or 15is can measure
what's happening on their system.

Victor - I think Eric was taking your original drawing at face value where you show one side of the Lane switch to be a ground. What Eric stated was correct for an electrical circuit based on what's on the drawing. You are right to try and figure out what Mother Rotax is doing for real since the Lane switch is nothing more than completing continuity between those two pins on HIC a and B.

Since I am going to use a 912is and the VPX I am watching this with a lot of interest.
